Hi All,
Just putting together a prototype Data Warehouse using the Nov CTP of SQL 2008 and was wondering if the following is a bug or if it's changed from SQL 2005. I've simplified the following examples.
Method 1 - Create table and then modify the column
Create the table using the following statement
CREATE
TABLETAB1
(
CalendarDate Date
NOTNULL,DayOfWeek tinyint
NOTNULL)
Go into management studio and modify the table, putting the following formula in the computed column specification of the "DayOfWeek" column.
(DATEPART(dw,CalendarDate))
This fails when you move the focus away from the computed column specification box with the error message "Error validating the formula for column DayOfWeek"
Method 2 - Create the table with the following statement, including the computed column specification in the SQL script
CREATETABLE
TAB2
(
CalendarDate Date
NOTNULL,DayOfWeek
AS DATEPART(dw,CalendarDate))
This works and the computed column is created ok.
Any ideas if I'm doing anything wrong in Management studio or if it's a bug?
Thanks
